Self-cleaning four fluorine type fluorocarbon coatings and preparation method thereof

The invention provides self-cleaning four fluorine type fluorocarbon coatings and a preparation method thereof. The method for preparing the fluorocarbon coatings includes a constituent A and a constituent B, wherein the weight ratio of the constituent A and the constituent B is 3-12:1-5. The constituent A comprises, by weight, the following ingredients: 35-75 of tetrafluoroethylene-vinyl ether copolymerized fluorocarbon resin, 0.2-5 of wetting dispersants, 0.05-0.6 of defoaming agents, 0.1-1 of leveling agents, 0.4-3 of antioxidants, 0.8-4 of self-cleaning auxiliaries of a compound which is capable of surface migrations and hydrolysis, and 3-18 of aromatic hydrocarbons, ketones or alcohols solvent. The constituent B comprises, by weight, the following ingredients: 55-95 of curing agents, 10-40 of the aromatic hydrocarbons, ketones or alcohols solvent. The problem existing in the prior art that hydrophobic coatings are increased in hydrophobicity but reduced in stain resistance is resolved.
